钢筋均匀锈胀力的若干问题研究

Research on corroded expansive force of the concrete reinforced bar

应用弹性力学理论推导出了钢筋均匀锈胀力的表达式,通过实例计算提出了理论计算公式存在较大 误差的问题,针对这一问题从锈蚀物物理参数的取值、锈蚀物形成阶段等多方面论述了产生误差的原因, 并提出了对理论公式的修正意见．

After deducing the expression of uniform corroded expansive force in steel bars based on mechanics of elasticity, the paper points out the problem of rather large error in the computing formula by an example. Then, the cause of the error is discussed in the physical parameter's value, formative stage of the corrosion products etc. After that, the suggestion is presented to amend the theoretical formula.
